Facebook

Embed code is code that is generated by a third-party website such as YouTube or Twitter, that a user can copy and paste into his or her own webpage. This embedded code will then show the same media, application, or feed on the user's web page as it does in the original source.

The Like Box plugin, supplied by Facebook, allows web page contributors to embed a live stream of their Facebook page into a webpage. Additionally, audience members can then choose to "Like" the stream topic.
